ALCM - Finned Square Anemostat

Dimensions in mm, weight in kg

These technical conditions state a row of the manufactured sizes and models of ceiling-,lamella- and square-type anemometers (further only anemometers) ALCM 250, 300, 400, 500, 600, 625. It is valid for a production, designing, ordering, delivery, assembly and operation.

I. GENERALLY

1. Description

Anemometers are the end exhausting element for the distribution of the air. They are used in the rooms of height approx. 2,6 - 4 m and they are suitable for the supply and outlet of the air. Anemometers have the face outlet areas from the fixed sectional lamellas /plates/ arranged horizontally and they are produced in the following sizes 250, 300,400,500,600 in five models of the face plates. They are supplied in a-workmanship for the horizontal connection via the connecting box, for the vertical connection on a square piping with the regulation (without connecting box) and in a compact workmanship with the regulation R1.

2. Workamanship

Anemometers are supplied in five models of the face plate by the sizes 250, 300,400,500,600 - basic I,H, L, U, by the size 625 in one model - basic model of the face plate.

Connection to the piping is possible as follows:

• via connecting box for the horizontal connection by means of a round inlet branch (a regulation flap can be fitted in the inlet branch, face plates are possible to attach and also disassemble by means of central screw /semi-finished bolt/)
• without the connecting box vertically on the square piping (anemometer is always equipped with a regulation in an adapter)

Anemometers are designed for the installation in the environment protected against the weather influences of class 3K5 according to CS Standard EN 60 721-3-3 and spaces BNV according to 1127-1.

V. PACKING, TRANSPORT, ACCEPTATION, STORAGE

Anemometers are supplied in the cardboard packages. They are transported in bulk by the usual means of transport. There is possible to transport the anemometers on pallets after agreement with the customer.

If the way of the acceptance is not determined in the order, the handing over of the anemometer to the forwarding agent will be considered as the acceptance. The anemometers have to be protected against the mechanical damage and weather influences during the handling , transport and storage. The anemometers are stored in the covered spaces, in the environment without the aggressive vapors, gases and dust.

The temperature in the range - 5 up to +40° C and the relative humidity maximum 80% must be kept in the facilities.

Manufacturer provides the guarantee for period 24 months from the date of dispatch for the anemometers.
